Question

100 = 8(4t - 5). Solve for t (in decimal form): *

Answer 1

The first step in solving the equation is dividing both sides by 8:

`100=8(4t-5)`
`(100)/(8)=4t-5`
`12.5=4t-5`

Adding 4 to both sides gives

`12.5+5=4t`
`17.5=4t`

Finally, dividing both sides by 4 gives

`(17.5)/(4)=t`
`t=4.375`

which is our answer!
